Clean, beautifully animated, 100% offline matrix calculator
Add, subtract, multiply, and find determinants of 2x2 and 3x3 matrices instantly
Matrix Calculator is a fast, offline math tool for solving 2x2 and 3x3 matrix problems in seconds. Add, subtract, multiply matrices, or compute their determinant with a single tap — no internet connection required, ever. Simply type values into the on-screen matrix grid, choose Matrix Size (2x2 or 3x3) and an Operation, then tap Calculate. Results appear instantly with a smooth animated reveal, whether it's a full result matrix or a single determinant value. Every screen is designed with a clean, modern light theme and hand-tuned animations — sliding selectors, staggered grid entrances, and a satisfying counting animation for determinant results — built entirely with native Flutter widgets. Under the hood, every calculation is powered by pure Dart math written from scratch. There are zero third-party runtime packages, which means a lightweight app, a smaller download, and one less thing that can break. Works 100% offline — no ads, no account, no internet permission, and no data collection of any kind. Nothing you type is ever saved, transmitted, or stored anywhere. Perfect for students learning linear algebra, engineers double-checking calculations, and teachers demonstrating matrix operations in class. Also handy for anyone who just needs a quick, reliable matrix answer. Simple enough for a first-year algebra student, accurate enough for a working engineer. Install once and start calculating in seconds — no sign-up, no setup. All features are completely free, with no in-app purchases, subscriptions, or hidden costs of any kind.
